Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, and in particular to a cargo ship for loading containers. Background Technology

[0002] Currently, container shipping, as a core mode of modern logistics, relies heavily on the structural design of cargo ships for its efficiency and safety. Traditional container ships typically employ fixed cargo hold partitions, using rigid bulkheads or supports within the holds to divide space for containers and achieve stacking positioning. However, this design has significant drawbacks in practical applications:

[0003] (1) Low space utilization: Fixed partitions occupy the effective volume inside the hold and it is difficult to dynamically divide the cargo hold space, resulting in low utilization of some areas. Especially when transporting non-standard containers, the cargo hold layout is difficult to optimize.

[0004] (2) Insufficient flexibility: Existing buffer devices are mostly permanent structures that are welded and fixed, and cannot be adapted and adjusted according to the size of the container or the type of loading and unloading equipment. When the loading of extra-wide containers or special cargo requires the removal of part of the buffer structure, large tools are often required, which increases the operation and maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to provide a cargo ship for loading and unloading containers, which can adjust the size of the container loading space through a detachable buffer assembly to accommodate more containers of different sizes and facilitate maintenance.

[0006] To achieve the above objectives, the present invention provides a cargo ship for loading containers, comprising:

[0007] A cargo hold, the cargo hold having a cargo cavity for loading containers;

[0008] Multiple partition components are arranged horizontally at intervals on the inner wall of the cargo cavity, and the container can be loaded between two adjacent partition components;

[0009] Multiple buffer components are detachably mounted on the separator component, one-to-one with each other.

[0010] Furthermore, the partition assembly includes two partition portions, which are respectively disposed on opposite inner walls of the cargo cavity, and the two partition portions are disposed opposite to each other.

[0011] Furthermore, the partition includes a connecting elbow plate disposed on the inner wall of the cargo cavity and a buffer connecting plate disposed on the connecting elbow plate. The buffer connecting plate extends in a vertical direction. The buffer assembly includes a plurality of buffer parts, which are spaced apart in a vertical direction on the buffer connecting plate.

[0012] Furthermore, the buffer connecting plate has a first end face and a second end face opposite to each other, and the buffer part includes a first buffer plate and a second buffer plate. The first buffer plate and the second buffer plate are respectively disposed on the first end face and the second end face. The first buffer plate and the second buffer plate are arranged side by side, and the extending directions of the first buffer plate and the second buffer plate are parallel to the extending direction of the buffer connecting plate.

[0013] Furthermore, both ends of the first buffer plate are provided with a first guide slope, and both ends of the second buffer plate are provided with a second guide slope.

[0014] Furthermore, the buffer portion also includes a mounting component, which includes a first bolt, a first nut, a second bolt, and a second nut;

A second receiving groove is provided on the second buffer plate, and a second through hole is provided at the bottom of the second receiving groove. The first bolt passes through the first through hole and the second through hole in sequence and engages with the first nut. The head of the first bolt is housed in the first receiving groove, and the first nut is housed in the second receiving groove.

[0016] A third receiving groove is provided on the second end face, and a third through hole is provided at the bottom of the third receiving groove. A fourth receiving groove is provided on the first buffer plate, and a fourth through hole is provided at the bottom of the fourth receiving groove. The second bolt passes through the third through hole and the fourth through hole in sequence and engages with the second nut. The head of the second bolt is housed in the third receiving groove, and the second nut is housed in the fourth receiving groove.

[0017] Furthermore, both the first and second receiving grooves are filled with an adhesive layer.

[0018] Furthermore,

[0019] The first buffer plate includes a first plate body and a first core plate. A first mounting groove is provided on the end face of the first plate body near the first end face. The first core plate is fixedly housed in the first mounting groove. The first core plate and the first plate body together form a second receiving groove. The second through hole is opened on the first core plate.

[0020] The second buffer plate includes a second plate body and a second core plate. A second mounting groove is provided on the end face of the second plate body near the second end face. The second core plate is fixedly housed in the second mounting groove. The second core plate and the second plate body together form the second receiving groove. The fourth through hole is provided on the second core plate.

[0021] Furthermore, a first through hole is provided on the first core board, a second through hole is provided on the buffer connecting plate, and a third through hole is provided on the second core board.

[0035] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] In the description of this invention, the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "lateral," and "longitudinal," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention. Those skilled in the art can understand the specific meaning of these terms in this invention according to the specific circumstances.

[0037] In the description of this invention, the terms "provided with," "set up," "connected," and "placed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, elements, or components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0039] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0040] like Figure 1-3 As shown, an embodiment of the present invention provides a cargo ship for loading containers, comprising:

[0041] Cargo hold 1, the interior of cargo hold 1 has a cargo cavity 11, the cargo cavity 11 is used to load containers;

[0042] Multiple partition components 2 are arranged horizontally at intervals on the inner wall of the cargo cavity 11, and the container can be loaded between two adjacent partition components 2;

[0043] Multiple buffer components 3 are detachably mounted on the separator component 2, one-to-one with each other.

[0044] It should be noted that the container loading spaces divided by the partition component 2 are interconnected.

[0045] Based on the above technical solution, multiple partition components 2 are arranged horizontally on the inner wall of the cargo cavity 11. The horizontally spaced partition components 2 divide the loading position of the container, avoiding the problems of high manufacturing cost and insufficient maintenance space caused by traditional partitions dividing the cargo cavity 11. The buffer components 3 are detachably installed on the partition components 2, which can be installed and used immediately, avoiding the maintenance difficulties caused by welding or gluing. Different sizes of buffer components 3 can be replaced according to the specific size of the loaded container to adapt to more containers of different sizes.

[0046] Preferably, the partition component 2 includes two partitions 21, which are respectively disposed on opposite inner walls of the cargo cavity 11 and are disposed opposite to each other.

[0047] Specifically, two adjacent partition components 2 use four partitions 21 to bidirectionally limit the four edges of the container, preventing the container from shifting horizontally relative to the cargo cavity 11 under the impact of waves.

[0048] More preferably, the partition 21 includes a connecting elbow plate 211 disposed on the inner wall of the cargo cavity 11 and a buffer connecting plate 212 disposed on the connecting elbow plate 211. The buffer connecting plate 212 extends in the vertical direction. The buffer assembly 3 includes a plurality of buffer parts 31, which are spaced apart on the buffer connecting plate 212 in the vertical direction.

[0049] Specifically, the buffer connecting plate 212 is formed by welding two angle steels together.

[0050] Multiple buffer sections 31 are arranged vertically at intervals on the buffer connecting plate 212. When a single buffer section 31 is damaged, it can be directly disassembled and replaced without disassembling the entire buffer assembly 3, which greatly reduces maintenance time. Moreover, for containers with different centers of gravity (the center of gravity of an empty container is high and the center of gravity of a full container is low), the material of the buffer section 31 at different positions can be adjusted or even the distribution density can be adjusted to specifically enhance the protection of vulnerable areas.

[0051] More preferably, the buffer connecting plate 212 has a first end face 2121 and a second end face 2122 opposite to each other, and the buffer part 31 includes a first buffer plate 311 and a second buffer plate 312. The first buffer plate 311 and the second buffer plate 312 are respectively disposed on the first end face 2121 and the second end face 2122. The first buffer plate 311 and the second buffer plate 312 are arranged side by side, and the extending directions of the first buffer plate 311 and the second buffer plate 312 are parallel to the extending direction of the buffer connecting plate 212.

[0052] The first buffer plate 311, the buffer connecting plate 212, and the second buffer plate 312 form a "sandwich" structure, which can improve the load-bearing capacity of the buffer connecting plate 212 and prevent the buffer connecting plate 212 from deforming due to repeated impacts from waves, thereby affecting its limiting ability.

[0053] More preferably, both ends of the first buffer plate 311 are provided with a first guide slope 31111, and both ends of the second buffer plate 312 are provided with a second guide slope 31211.

[0054] The first guide ramp 31111 and the second guide ramp 31211 form a progressive guide channel. The container edges fall and contact the guide ramps. The guide ramps can guide the container into the cargo cavity 11, avoiding edge collisions between the cargo cavity 11 and the container during hoisting, which could cause unnecessary damage to the container or the cargo cavity 11.

[0055] More preferably, the buffer portion 31 further includes a mounting member 32, which includes a first bolt 321, a first nut 322, a second bolt 323, and a second nut 324;

[0056] A first receiving groove 21211 is provided on the first end face 2121, and a first through hole 21212 is provided at the bottom of the first receiving groove 21211. A second receiving groove 31212 is provided on the second buffer plate 312, and a second through hole 31221 is provided at the bottom of the second receiving groove 31212. A first bolt 321 passes through the first through hole 21212 and the second through hole 31221 in sequence and engages with a first nut 322. The head of the first bolt 321 is accommodated in the first receiving groove 21211, and the first nut 322 is accommodated in the second receiving groove 31212.

[0057] A third receiving groove 21221 is provided on the second end face 2122. A third through hole 21222 is provided at the bottom of the third receiving groove 21221. A fourth receiving groove 31112 is provided on the first buffer plate 311. A fourth through hole 31121 is provided at the bottom of the fourth receiving groove 31112. The second bolt 323 passes through the third through hole 21222 and the fourth through hole 31121 in sequence and engages with the second nut 324. The head of the second bolt 323 is housed in the third receiving groove 21221, and the second nut 324 is housed in the fourth receiving groove 31112.

[0058] The head of the first bolt 321 is housed in the first receiving groove 21211, and most of the threaded portion of the bolt is housed in the first through hole 21212 and the second through hole 31221. The first nut 322 is housed in the second receiving groove 31212, which is connected to the cargo cavity 11. Therefore, under the sealing effect of the first nut 322, most of the first bolt 321 will not be exposed to the air to avoid corrosion from seawater vapor. When the first nut 322 is corroded, it can be directly removed and replaced. In this process, it is not necessary to readjust the position of the second buffer plate 312. Since the first bolt 321 passes through the second through hole 31221 and has a limiting effect on the second buffer plate 312, the operation is convenient.

[0059] It should be noted that the second bolt 323 and the second nut 324 have the same technical effects as the first bolt 321 and the first nut 322, which will not be elaborated here.

[0060] More preferably, both the first receiving groove 21211 and the second receiving groove 31212 are filled with an adhesive layer 4.

[0061] Specifically, the adhesive layer 4 is made of epoxy resin.

[0062] After the adhesive layer 4 fills the first receiving groove 21211, it seals the first nut 322 and the first bolt 321 without any dead angles, blocking the intrusion path of marine water vapor. The adhesive layer 4 has viscoelastic properties, which can absorb the vibration generated by the turbulence of the cargo ship and the impact of loading and unloading, and reduce the dynamic load transmitted to the first bolt 321. After the adhesive layer 4 is cured, it adheres to the surface of the first nut 322, which can prevent the first bolt 321 and the first nut 322 from loosening and ensure the stability of the installation of the second buffer plate 312.

[0063] It should be noted that the adhesive layer 4 in the second receiving groove 31212 has the same technical effect as the adhesive layer 4 in the first receiving groove 21211, which will not be elaborated here.

[0064] More preferably,

[0065] The first buffer plate 311 includes a first plate body 3111 and a first core plate 3112. A first mounting groove 31113 is provided on the end face of the first plate body 3111 near the first end face 2121. The first core plate 3112 is fixedly accommodated in the first mounting groove 31113. The first core plate 3112 and the first plate body 3111 surround to form a second receiving groove 31212. A second through hole 31221 is provided on the first core plate 3112.

[0066] The second buffer plate 312 includes a second plate body 3121 and a second core plate 3122. A second mounting groove 31213 is provided on the end face of the second plate body 3121 near the second end face 2122. The second core plate 3122 is fixedly accommodated in the second mounting groove 31213. The second core plate 3122 and the second plate body 3121 surround to form the second accommodating groove 31212. A fourth through hole 31121 is provided on the second core plate 3122.

[0067] The first core plate 3112 serves as a pad for the first nut 322, which can reduce the preload loss of the first nut 322, prevent the first nut 322 from becoming loose from the first core plate 3112 when the cargo ship is rocking at sea, and ensure the stable meshing of the first nut 322 and the first bolt 321.

[0068] It should be noted that the second core board 3122 has the same technical effect as the first core board 3112, which will not be elaborated here.

[0069] More preferably, a first through hole 31122 is provided on the first core plate 3112, a second through hole 2123 is provided on the buffer connecting plate 212, and a third through hole 31222 is provided on the second core plate 3122. The first through hole 31122, the second through hole 2123, the third through hole 31222, the first plate 3111, and the second plate 3121 enclose a receiving space. A tenon 5 is fixedly welded to the bottom of the second mounting groove 31213 of the second plate 3121. One end of the tenon 5 passes through the third through hole 31222, the second through hole 2123, and then into the first through hole 31122.

[0070] After the mortise and tenon 5 passes through the first through hole 31122, the second through hole 2123, and the third through hole 31222, the first buffer plate 311, the second buffer plate 312, and the buffer connecting plate 212 form an interlock, which together resists the vertical shear load and can reduce the risk of slippage failure of the first buffer plate 311 and the second buffer plate 312.

[0071] More preferably, the buffer portion 31 includes two mounting members 32, which are spaced apart in the vertical direction, and the tenon 5 is disposed between the two mounting members 32.

[0072] The two mounting pieces 32 bear the load in the vertical direction, transforming the traditional single-point force into a double-point support. The mortise and tenon piece 5, as the third fulcrum, can effectively disperse the shear force generated by the impact of waves and prevent the bolt connection from failing due to stress concentration.

[0073] The installation process of the first buffer plate 311 and the second buffer plate 312 is as follows: A first bolt 321 is inserted into the first receiving groove 21211 and the first through hole 21212 of the buffer connecting plate 212, with the head of the first bolt 321 abutting the bottom of the first receiving groove 21211. A second bolt 323 is inserted into the third receiving groove 21221 and the third through hole 21222 of the buffer connecting plate 212, with the head of the second bolt 323 abutting the bottom of the third receiving groove 21221. The mortise and tenon 5 on the second buffer plate 312 is aligned with the second through hole 2123, and the second through hole 31221 is aligned with the first bolt 321. Bolt 321, install the second buffer plate 312 onto the buffer connecting plate 212, tighten the first nut 322 on the first bolt 321, align the first through hole 31122 of the first buffer plate 311 with the part of the mortise and tenon 5 protruding from the buffer connecting plate 212, align the fourth through hole 31121 of the first buffer plate 311 with the second bolt 323, install the first buffer plate 311 onto the buffer connecting plate 212, tighten the second nut 324 on the second bolt 323, fill the first receiving groove 21211 and the second receiving groove 31212 with adhesive layer 4, and complete the installation after the adhesive layer 4 has solidified.

[0074] In summary, the present invention provides a cargo ship for loading containers, wherein multiple partition components 2 are horizontally spaced on the inner wall of the cargo cavity 11. The horizontally spaced partition components 2 divide the loading position of the containers, avoiding the problems of high manufacturing cost and insufficient maintenance space caused by traditional partitions dividing the cargo cavity 11. The buffer components 3 are detachably installed on the partition components 2, which can be installed and used immediately, avoiding maintenance difficulties caused by welding or gluing. Different sizes of buffer components 3 can be replaced according to the specific size of the loaded containers to adapt to more containers of different sizes.

[0075] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
